ABSTRACT
Context. Solar coronal bright points have been studied already for more than three decades but some fundamental questions about
their formation and evolution still remain unanswered.
Aims. Our aim is to determine the plasma properties of a coronal bright point and compare its magnetic topology extrapolated from
magnetogram data with its appearance in X-ray images.
Methods. We analysed spectroscopic data obtained with EIS/Hinode, Ca II H and G-band images from SOT/Hinode, UV images from
